In a large mixing bowl stir together flour, salt, and yeast. Add water and mix until all flour is moist.Cover bowl with plastic wrap and set aside for 12 to 18 hours, overnight.

Heat oven to 450 degrees. When oven is preheated put large casserole dish with lid in oven to heat up (a dutch oven would also work) for 30 minutes. Scoop out dough onto floured surface and shape into a ball. Cover with plastic wrap and let dough rest for 30 minutes.

Take the hot dish out of the oven and place dough inside (you do not have to grease the dish, if it is hot the dough will not stick).
